[PyQt] printing in Windows not working - tested on Vista 32 bits

Hello!
I use (Ubuntu 64bit 10.10 + PyQt 2.7 + Python 4.8.2) and QPrintDialog
works perfectly. Including the ability to save in PDF. But when tested
on Windows Vista 32bits simply nothing appears, not even an error
message. The application works perfectly, but when calling the
QPrintDialog, nothing ...
Already installed to the latest stable version of PyQt 4.8.2 on sight,
but still the same behavior. Has been there? Is it necessary for some
differentiation in the code that runs on windows? Already searched the
internet but did not.
Thanks,
Rodrigo
My code:
------------------------------------------------------------------------
def print(self, string):
printDialog = QPrintDialog(self.printer, self)
if printDialog.exec_():
filePrint = QTextDocument()
filePrint.setDefaultFont(QFont('Liberation Sans',10))
filePrint.setHtml(string)
filePrint.print_(self.printer)
------------------------------------------------------------------------
